The story of Mark Cerny and Sony Japan Studio’s PlayStation 4 launch title Knack revolves around a little creature named… Knack.

Goblins and humans have lived together on Earth in separate societies since the goblins invaded Earth a few years prior to the game’s events. But when the goblins invade a human settlement, it’s up to Knack to find their hideout and discover how they got access to advanced tanks and airships.

Knack will be aided by a number of characters on his journey:

The Doctor – The inventor that brought Knack to life thanks to the mysterious power of the ancient relics.

Lucas – The Doctor’s teenage assistant.

Ryder – Lucas’ uncle, who is also a world-famous explorer.

Viktor – A billionaire industrialist who made his fortune mining the ancient relics that provide power for electricity, machinery, vehicles, and more. He has bigger ambitions, however, placing him at odds with Knack and crew. This means you’ll be facing not only the goblin soldiers, with their tanks, mechs, and airships, but Viktor’s own army of soldiers and robots as well.

Throughout the story, you’ll play through a variety of stages and environments, including caves, forests, cities, and airships, within which challenging boss battles await.

Knack is a creature made of relics. He can absorb more relics as you progress through the game, growing from his original three-foot tall stature to six, 15, and even 30 feet tall. Just like relics, Knack can also absorb other materials, like ice, metal, and wood.

Ice Knack is first acquired in a cave of ice. When you exit the cave, you’ll still have your ice equipped, giving you a power advantage, but you only have until the ice melts to defeat tough enemies. Metal Knack is an “extremely powerful” form, but the magnetism could lead to “some interesting problems.” Wood Knack, one of Knack’s biggest forms, burns easily, which you could use to access “some interesting areas.”
